率が低下する欠点がある。However, even though it is initial rainwater, it retains a certain level of water quality, and if its use is limited, it is worthwhile to make a separate tank for storage and reuse. In addition, washing water and bath water, which require a high degree of cleanliness, may cause the growth of bacteria and dirt when there is a trace amount of organic matter, and in the case of washing water, the cleaning effect of the detergent may be reduced. Therefore, when using it, it is necessary to purify it according to the application. In addition, washing machine and bathtub,
If polluted water remains after using the toilet, various bacteria grow, and putrefactive smell and dirt remain, so it is necessary to suppress the growth of various bacteria. In addition, particularly when it is supplied to the washing water, when there is a so-called hardness component such as calcium ions or magnesium ions, the washing action of the detergent is reduced, and thus it is preferable to remove the detergent. In addition, if the rainwater storage tank or the supply pipe is dirty, the quality of the reused water deteriorates, and it is necessary to prevent the growth of bacteria that cause the dirt. In addition, when using the potential energy of rainwater as electrical energy, the rainfall flowing directly down the roof from the rain gutter changes the flow velocity depending on the amount of rainfall, so when the flow rate is small or the rainfall becomes excessive, Since the rotation speed of the rotor of the generator is not stable, there is a disadvantage that the conversion efficiency is reduced.

効に利用できる。The initial rainwater is pumped up by the pump 21 and is used without treatment for watering without any problem even if there is a dirt component. Rainwater after the initial rainwater is used for washing water, bath water and toilets. When used as washing water or bath water, dirt components are purified by a purifying device 22, sterilized by a sterilizer 23, and sent. Furthermore, in the case of washing water, calcium ions and magnesium ions that inhibit foaming are removed by passing the washing water through the ion exchange device 24. Further, in the case of use in a toilet, rainwater after the initial rainwater may be directly used without treatment as shown in FIG. 1, or as shown in FIG.
The water may be purified and sterilized by the sterilizer 23 and sent. At that time,
Whether or not the sterilizer 23 is always operated is preferably set to be switchable depending on the degree of dirt in the toilet. Rainwater can be used effectively by performing treatment appropriate for the water quality at each destination.

Microorganisms proliferate there and generate mold odor and putrefaction odor. Therefore, in order to prevent the propagation of microorganisms that cause accumulation of dirt components, water from which metal ions having a bactericidal action are eluted is supplied from the sterilizer 23 during washing and bathing and periodically, or adjusted to pH 3 or less. Supply the electrolyzed water. Similarly, toilets are regularly supplied with sterilizing water during use to prevent contamination due to the propagation of germs. Similarly, the initial rainwater storage tank 11 and the rainwater storage tank 12 after the initial rainwater are stored.
Also, water having a sterilizing action is periodically supplied from the sterilizer 23 to prevent the propagation of various bacteria.
